After that observation I nocticed another thing. Its similarity to Charkra in the Naruto World. I noticed how in order for the characters to use jutsus, they must channel their chakra through their body and use the willpower of the spirit in order to Preform the technique. Also in the Naruto world, jutsus weaken you a slight bit. Thus having some side affects justl ike psi skills.
To this information, I thought of a possibility that training yourself physically and mentally would help you control your psi more, and give you more stamina to do the job.
Well thats what I wanted to show you guys and I hope to get to know you guys a it more.
